COOLING TOWER.

Application flled April 27, 1927. Serial No. 187,016.

My invention is a cooling tower usually used for cooling water in industrial and other operations.

An object of my invention is the construction of a cooling-tower particularly adapted for cooling water in industrial operations in which the tower is made in a series of units which may be connected together to form a tower of any height desired or if it is desired to decrease the height the units may readily-be removed one after the other until the desired amount of cooling of the water is obtained.

A more particular object of my invention is the construction of a cooling tower having a series of louvers, these being arranged in rectangular or other suitable shape in units, and each unit set of louvers having a mounting to allow stacking of the various units one on top of the other, the mounting forming a rigid structure and spacing the louvers the proper distance apart.

More specifically an object of my invention is the construction of louver units having corner legs or brackets, these legs or brackets supporting an upper louver unit on the unit immediately below and each corner leg where it attaches to a louver unit forming the bearing surface for the next unit above.

In constructing my tower I form the lou ver units preferably of sheet metal, such as galvanized iron, the lower edge of the units being spaced inwardly from the upper portion so that when the units are stacked to form a tower a proper air circulation may be obtained. The corner legs or brackets are preferably formed angular, and of sheet metal, extending along the upper edge of a louver unit and having alower part which may be riveted to a louver unit next below. These sheet metal legs have braces which are bent inwardly and rest on the underneath louver unit, thus giving a rigidsupport independent of the bolting or riveting of the units together.

My invention will be more readily understood from the following description, together with the drawings, in which:

Figure 1 is a perspective view of a cooling tower constructed in accordance with myinvention.

Figure 3 is a detail elevation of a corner of the tower.

Figure 4 is a horizontal corner detail on the line 1- 1 of Fig. 2 in the direction of the arrows.

Figure 5 is a top plan view of a corner post or bracket.

Figure 6 is an inside elevation of such post or bracket, taken in the direction of the arrow 6 of Fig. 5.

In constructing my tower- I preferably have a tray 11, whichmay be constructed in any suitable manner and is preferably made of sheet metal, and above this tray I secure a plurality of louver units 12. Each of these units is preferably'constructed of sheet metal having sides 13 with a short "vertical section 1 1 at the top and an-inturned flange 15 which may be doubled over in the form of an outward fold 16. The lower part 17 of each side wall below the vertical part 14 is inclined inwardly and at the lower extremity there is an inwardly turned flange 18 forming the lower edge 19 of the louver unit. The lower part of the walls'are inclined'inwardly at a sufiicient angle so that the space 20 between the inside edge 21 of the flange 15 of a lower unit is suflicient to allow free flow of air. The lower edge 19 is also preferably in a plane below the flange 15 to prevent outward blowing of water. The corners 22 of the louver units preferably have a seamed joint but these corners may be connected in any suitable manner.

Attachedto the corner of each louver unit at the top is a leg or bracket 23. I find a suitable structure for this leg or bracket may be made of sheet metal having a main leg portion 24 with an inwardly turned flange 25 at the top, this flange fitting over the flange 15 of the louver unit at the corners, the legs being bent with right angular corners 26 for a rectangular type of louver. Rivets or other fastenings 27 secure the upper part of the leg to its louver unit on the vertical part 1 1 of the side wall. The foot 28 of each of the legs extends downwardly over a leg next below, as indicated by the numeral 29 in Figs. 1 and 3, and is secured by'rivets or the like which extend through such leg part of an upper leg and through the upper part 31 of a lower leg and also through the vertical part 14 of the louver walls, such connection being clearly shown in liligsfQ, 3 and 4.

In order to brace the legs and to support an up er ower un nde n nt of th riveted connection I proyide brace portions or webs 82 which are'formed integral with the sheet metal part of the leg and are bent or inclined inwardly so that each of these braces has its lower edge 3 3 resting on top of the flange 25 of the leg structure on the louver unit next. below. This edge 33 preferably is positioned at right angles to the sides of: the louver unit.

In some cases it is desirable that the leg or bracket 34 on the lower louver unitbe longer-"than the others so as to" extenddown? Wardly into the tray 11, resting on the floor of such tray, "and being secured at the corner of the tray by rivets 35 The louver units may be made up with corner legs orbrackets attached to each unit:

and such units may be stackedgup one on top of theother, rivetmg or otherwlse securing an upperilegtofthe unit next below and so: on until a suflicient hei ht of tower is 0bto" the louver= units after the structure is built 'up, in whichcase the louver units may be convenientlypacked for" shipping by stacking them one inside of another. legs or-'bracketsare also'of such character that they maybe stacked together in a convenient mannerfor shipping.

From the above construction it will be seen that Ihave developed a simple type of cooling tower that is "adapted for many types of Water Ol' O tlIQI' liquid cooling. The

l'egor bracket structure may be'adapted to wooden louvers as well as to sheet metal louvers. Also, if desired, the leg structures maybe made ofwo odfio r other material suitably shapedsothat each louver unit may be built up one'on top of the other.
